Since you have identified the IP Address for IMSS server,when you will be changing the ISPs, make sure that MX has Primary and Secondary records for IP addresses as follows:
  • ISP1 -  -- Primary -- 10
    ISP2 - -- Secondary 20
    ISP3 - --- 30
    ISP 4- ---- 40
for your domain.
 This would take care of things, if first IP would be unavailable, then mails will go to next IP

i have registered my domain with networksolutions. If i go to mail server MX records,  I don't have option to give one name with multiple IP address with metric.

Can you clarify how to add ?

In the screenshot, see keep on adding the IP Address of the Servers in the Mail Server Text Box and Priority will be 10, 20, 30, 40
But is this the actual screenshot of your domain name?

Also please ask your ISP to do it, they will take a minuite. Raise a NetworkSolution Support Ticket and ask them to add Secondary MX Entries.
Do not worry it is a simple entry, but without control I can't really helpl you how your ISP has designed their Control Panel
